Stalling/dying by mthompson1

I have an 88 S10 2.8 fuel injected 5 speed manual transmission. Truck will start, but will not stay running unless you feather the gas to try to keep it running. Once it backfires through the carb, it throws a code 24, which is a speed sensor. I cannot find this speed sensor. They say it is on the tail end of the transmission. There is no electric going to the back of the transmission. Replaced fuel pump, fuel filter, cleaned throttle body injectors, checked all wiring, grounds...still having problem. Is this possibly a computer problem?

99 chevy S-10 engine cuts out by bethsman

I have a 99 chevy S-10 with the 2.2 engine, manual trans. and 135K miles. My problems started about 2 weeks ago, when driving at a steady speed if I try to accelerate the engine tries to die. The best way I can describe it is, if you press the brakes to stop and don’t press the clutch that jerking motion the vehicle makes, it happens for a second then everything goes back to normal. Except for 2 times it did something different. One of the times I was in fifth gear and went to accelerate nothing happened (engine did not bog down or speed up). The gas pedal was all the way down to the floor after about 45 seconds the truck sped up. Then the other day I was making a right hand turn and all my lights dimmed and the oil gauge on the dash went to zero, my battery gauge went to about 9 I lost power steering. I thought my truck had stalled but the engine was still running and sounded really bogged down. After a minute of coasting the truck went back to normal and ran good the est of the way home. I have not drove it since. The plugs, wires are good. replaced the fuel filter, got gas from a different station but it did not help. I’m lost on what the problem is. I have been told it could be the fuel pump, short circuit, cam shaft position sensor, timing chain, injectors, or the computer. I'm getting no check engine lights. If you could give me any help it would be greatly appreciated. Thanks again for your help.

anyone having an electrical problem on a chev s10 should read this. This actually happened to me. While crossing the burnside bridge my engine started cutting out. then the amp meter and speedometer went wacky. Then the fuel gauge went haywire, oil pressure fell to zero. I almost didn't make it home. A diode had gone out in the alternator. With everything being electronic these days the computer wasn't receiving info from the sensors. 2 years later while driving down the freeway the engine suddenly quit. I knew it was electrical. After a few minutes I found the problem. The negitive terminal on the battery had vibrated loose. Thats right! every eletronic system in the truck fails all at once with just one screw loose. If this were a military vehicle GM would be buying back everyone sold as new defective.

Hey I was wondering if you ever got this resolved. I have the same exact truck and it's doing the same thing. I can't figure it out. Can you please let me know what you did to fix this problem. Thanks.

ive been dealing with this problem for months now...replaced almost everything...fuel pump, spider injector(which was conversion to multiport), fuel filter, aif filter, spark plugs(twice) spark wires, distributo cap and rotor as well as distributor itself, alternator, battery, ignition coil, map sensor, catalytic convertor, but the truck still wants to buck and cut out when cruising on highway and either going uphill and putting it under a load...or just when i pass a car and come off the gas...does it one day, then not the next, then does it for a week straight, then it goes off....only thing is one day when i shimmied the main harness that runs across the intake plenum it kinda got better for a day or two....did it again and i got no help....im about two steps away from driving it over a cliff i need some help!!!

Chevrolet S-10 stalling/dying issues by gk10

I took my S-10 to three shops (Chevy dealer was the last one). Bottom line is that the fuel pump was not holding pressure while driving. I bought an "original equipment" fuel pump online and had the first shop install it. That resolved the problem. NOTE: Don't skimp on the replacement fuel pump - the off brand ones go bad within a few months. Good info from the mechanic.

I'm having the same problem but hasn't thrown that code. Have you ever found the problem?
